Lifetime license is an add-on cost to the actual HOME/PRO/ENTERPRISE licensing costs, which then prices them out of the market, especially when so many other great alternative or similar applications are still free. The freeware version of this application, you cannot even do studies, analysis, etc. which makes the freeware version useless, why install if all you are going to get are small subset of nodes and not be able to analysis, determine packet integrity, heat-map, etc. I went with SpiceWorks, their free version is actually free and does all the tasks that NetSpot PRO for free.
